.HEELLCUTTER 'i To all whom t may concern.'

Be it known that I, WILLIAMV J. NEsBiTT, a citizen of the United Statesof America, residing at Los Angeles, county of Los' Angeles, State ofCalifornia, have invented a certain new and useful `Heel-Cutter; and Ido hereby declare the following to be a full,"c1`ear,'and exactdescription of the invention, such as will enable others skilled* in theart to which it appertains to make and use the saine. l

This invention relates to heel cutters; more particularly toimprovements in the heel cutter which is disclosed in my applicationSerial No. 172,537, filed June 1917.

The main object of this invention is to provide a novel and improvedconstruction in which the dished stiffening plate is mounted on a sleeveso that. the stiffening plate can be adjusted relatively to the circularsaw by adjustment of the sleeve longitudinally of the shaft.

Other objects and the advantages of the invention will be yapparent tothose skilled in the art from a careful consideration of the followingdescription of preferred forms of construction embodying the invention,taken in connection with the accompanying drawings in which- Figure 1 isa side elevational View of the heel cutter and its mounting; Fig. 2 isan end elevational view of the same; Fig. 3 is an enlarged brokensectional view taken on the line 3 3 of Fig. l; Fig. 4 is a brokensectional view showing another form of construction embodying theinvention; and Fig. 5 is a similar view with the stiffening plate inchanged position.

In the drawings similar parts are designated by like reference numerals.

Referring to Figs. 1, 2 and 3 of the drawings, the bracket 10 isprovided with the bearings 11 and 12 for the shaft 13 which may beoperated by suitable means such as the sprocket wheel 14 which latter ismounted fast on the shaft 13 between the bearings 11 and 12.

In order to obtain the best results in cutting the leather and nailsinthe heel of a boot or shoe the circular saw 15 must be comparativelythin, and it is preferably of the type that is ordinarily used forsawing metal. The circular saw 15 is provided with teeth 16 on itsmarginal portion 17, and it has its central portion fitted on thethreaded reduced end portion 18 of the shaft Specification of LettersPatent.V

13. A nut 419 onlthe'reducedportionlS is screwed up tightly against` thefront face of thecircularfsaw 15 to press tlielrear face of the circularsaw 15 against the shoulder 20 onthe` shaft 13. The-circular saw 15 ispreferably locked to the shaftv 13S by means of the pins 21 which extendforwardly from the shoulder 20 and fitlinthe openings 22 on the centralportion of the circular saw 15.

The stilfening plate 23 is mounted on the sleeve 24 so that it can beadjusted longitudinally of the shaft 13; said stiffening plate being ofgradually reduced thickness from its central portion to its periphery 25which latteris disposed adjacent to the inarginal portion 17 of thecircular saw 15. The front face 26 of the stifening plate 23 is dishedand disposed adjacent to the rear face of the circular saw 15. As shownin this instance the sleeve 24 is threaded to Y screw on the shaft 13,and said sleeve 24 has a portion 27 thereof formed so that it can beturned by a wrench to adjust the'J stiening plate 23 relatively to lthecircular saw 15.

In the form of the construction shown in Figs. 4 and 5, the bushingE 28of the shaft bearing 12 has a'threaded.;l extension 29 on which isvfitted the threaded sleeve 30 on which the central portion thestiffening plate 23 is mounted; a suitable ball bearing 31 beingprovided for the stili'ening plate 23 and interposed between the sleeve30 and the stifliening plate 23. The sleeve 30 hasthereon a collar 32provided with flat faces so that the sleeve 30 can be turned by a wrenchto adjust the stilfening plate 23v relatively to the circular saw 15.

From the foregoing it will be understood that the sleeve 27 or thesleeve 30 can be adjusted in order to move the stiffening plate againstthe circular saw 15 and dish the latter to the desired degree. Unlessthe front face of the circular saw 15 is dished so that the marginalportion 17 of the saw 15 clears the intact part 33 of the heel 34,

the saw 15 will not cut in a straight line against the intact part 33because of the nails and uneven texture of the heel 34 which deflectsthe teeth 16 toward the slice 35 which is being cut 0H of the heel andbears with less resistanceV against theteeth 16 than does the intactpart 33. The plate stiffens the comparatively thin circular saw 15, andit inclines the marginal portion 17 forwardly so that the points of theteeth 16 are directed toward the intact part 33 of the heel 84 so thatthe teeth 16 are adapted to springback against' the intact part 33 Whenthey are deflected from said intact" Copies oi this patcntmay be thecircular saw as and for the purpose set forth.

i 2. The combinaion With a shaft7 of a bushing tted on said shaft, asleeve arranged on said bushing and adjustable longitudinally of saidshaft, a circular saw mounted on said shaft,` and a dished stiffeningplate mounted on said sleeve,substantially as and for the purpose setforth.

In testimony whereof I yhave. signed my name to thisspecification at LosAngeles, county of Los Angeles, State of California, this 6th day ofSeptember A. D 119l7.
